First-Order Hold

Implement first-order sample-and-hold

Library

Discrete

Description

The First-Order Hold block implements a first-order sample-and-hold
that operates at the specified sampling interval. This block has little
value in practical applications and is included primarily for academic
purposes.

This figure compares the output from a Sine Wave block and
a First-Order Hold block.

Data Type Support

The First-Order Hold block accepts and outputs signals of type double.
For more information, see Data Types Supported by Simulink in
the Simulink® documentation.

Parameters

Sample
time

The time interval between samples. See Specify Sample Time in
the online documentation for more information.
